Back End Core Bound

Back End Core Bound

Cycles the back end is bound on core non-memory issues (i.e. Out of Order (OOO) resource and execution)

RELEVANCE:

This metric represents how often the pipeline was back end bound on core non-memory issues. This may indicate that you have run out of OOO resources or are saturating certain execution units (e.g. the use of FP-chained long-latency arithmetic operations) which can limit performance.

The equation to calculate Core Bound is:

Core_Bound = Backend_Bound_at_EXE – Memory_Bound

EXAMPLE:

For instance, if you have excessive use of a particular execution unit such as the divider, this would cause the core bound to be high.
